Crushing injury of lower leg (S87)

The ICD-10 code S87 and its subcodes classify crushing injuries specifically affecting the lower leg, including the knee and surrounding areas. These codes are used to document the precise location and phase of treatment for crush injuries, such as the initial encounter, follow-up visits, or sequelae (long-term effects).

The section covers variations like the crushing injury of the knee (S87.0) and lower leg (S87.8), with further detail by side (right or left) and by specific type of encounter indicated by seventh characters (e.g., S87.00XA for an initial unspecified knee injury). Common synonyms such as "crush injury," "closed crush injury," and "open crush injury" of the knee or lower leg help clarify that these codes include all crush-related trauma of these limbs. Using the correct ICD-10 code for crushing injury of lower leg ensures accurate medical documentation for treatment stages and injury specifics, essential for patient care and clinical reporting.

Instructional Notations

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

  • code(s) for all associated injuries

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • crushing injury of ankle and foot S97

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category S87

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

  • D - subsequent encounter
  • S - sequela
